RESILIENT PLATFORM FOR -STRIKI1\TG-BAGS.

Specification of Letters Patent. 2 Patented Feb. 29, 1916.

Application filed July 16, 1915. Serial No. 40,205.

- To all whom it may concern:

Be it known that I, Bonner N. DIEHL, a citizen of the United States, and a resident of Hanford, in the county of Kings and State of California, have invented a new and Improved Resilient Platform for Striking-Bags, of which the following is a full, clear, and exact description.

My invention relates to a structure on which a striking bag or a punching bag is mounted, the structure being generally termed a striking platform, and receiving the impact of the bag when struck.

My invention relates particularly to a striking platform in which the element presenting a surface or surfaces is resiliently supported to yieldingly receive the impact, and by reaction to exert a return force on the bag. The invention includes also a novel means for mounting the platform on a support.

Reference is had to the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the views,

and in which Figure 1 is a perspective view of a striking bag platform and its supporting means, embodying my invention, showing a bag sus pended thereon; Fig. 2 is a fragmentary vertical section; Fig. 3 is a plan view of the platform, the supporting means being omitted; Fig. 4: is a detail vertical section showing a modification of the platform supporting means; Fig. 5 is a perspective view of the adapter or member carrying the swivel for securing the bag; and Fig. '6 is a sectional side elevation of a modified form of the adapter.

Referring particularly to Figs. 1, 2, 3 and 5, my improved platform includes a rigid center 10 preferably in the form of a cast steel plate, to which are secured, by rivets 11 or other means, radially disposed arms 11 in the form of plate springs which carry at their outer ends a striking rim 12. The arms 11 curve away from the plane of the plate 10 so as to support the striking rim 12 in a parallel plane slightly distant from the plate. Any suitable means may be employed to secure the rim to the resilient arms 11, such as bolts, pins or rivets 13, and washers 14.

The means for supporting the striking platform are as follows: A stud bolt 15 re- The bracket arm is formed at the end opposite the head 20 with a flange 21 or given other suitable formation whereby to secure the arm to a wall or other support. Lengthwise of the bracket arm strengthening ribs 21 may be provided. On the bracket arm 21 beyond the head 20 is formed a fork presenting arms 22 that incline upwardly and forwardly, as best seen in Fig. 2, and which diverge from each other, as seen in Fig. 1. The fork members 22 receive studs or braces 23 having nuts 24 to secure them to the members 22, and at the opposite ends flanges 25 or equivalent members are produced on the braces, whereby to secure the same to the wall or support at points distant from the bracket arm 21. p

In order to mount a striking bag A. on the platform, I employ an attachment 26, termed an adapter, the same being preferably in the form of a tube and having an enlarged upper end internally threaded to take onto the threaded boss 19 and accommodate the nut 17. The element 26 is squared or otherwise made angular as at 26 whereby the same wrench employed to turn the various nuts referred to will serve to screw and unscrew the said element. Said element 26 carries a swivel 27 which is secured by a ferrule 28 having threaded engagement with the element 26. The swivel 27 is provided with an orifice 29 for connection of a cord (1 or the like, for supporting the striking bag A, the said cord being knotted or having other enlargement within the swivel 27 to prevent withdrawal of the cord.

By. the described arrangement it will be obvious that the bag will be centered within the rim 12 and upon being struck will strike the said rim which, o'ing to the resiliency of the arms 11, will give an active rebound to the bag. It will be seen from Fig. 2 that the resilient arms 11 are of re- In Fig. 4 an extension member 30 is inter= posed between the stud bolt 15 and the plate of the platform. At the upper end'said extension member has a threaded bore to take onto the lower end of the stud 15. the

' nut 17 being omitted. At the lower end the sage of the cord at f om the bore 2 to be understood that the stud bolt 15 may extension member is formed with an externa y th a d stem 3 wh h extends through the plate 10 and receives a nut 32 o bea ga t he und s de of t boss 1, Said boss 19 receives the adapter 26 in the sa e ma ner as n he rst descri ed construc on- In F g- 6 I hav shown a odified form o the adapter, nd cat d y he ha acter 6*, he same receiving a n pple 28 having an e ongated bo e 8" for the passage of the cord a and accommodating Within the same a cup 27*- hav ne an'orifice 29 for the. t is take into floor or wall plate having a threaded orifice or socket, to receive said bolt when it is not desiredito employ the bracket arm 21.

Having thus described my invention, what I claim as new anddesire to secure by Let ters Patent, is: r

1. A platform for striking bags, including a strikingirim, a rigid portions within the rim provided with'means to secure a striking bag, and arms connecting the rim with said rigid portion,..saidarms being in the form of plate, springs having resiliency toward the outer ends; 1

2. A platform for striking bags, and supporting means therefor, including a bracket arm forked at its outerend, the fork mem bers incliliingoutwardly and upwardly from the body of thebracket arm and diverging from each other, braces detachably con,- nected at one end'to said members, and

adapted to be secured at its opposite end to a support, a platform having a striking rim, and a boltdetachably connecting said platform and bracket arm, adjacent to the said fork members. i I

3. A'platformflfoir a striking bag, and support ng means therefor, including abracket arm, a bolt connecting the bracket near one end with the platform above the latter, and a fitting having detachable engagement with the platform at the underside and presenting a rest accommodating the lower end of the bolt, and means carried by thesaid fitting to support a striking bag. 7

al A platform for striking bags, including a' supporting member adjacent to' 'oneface of the platform, means forming a detachable connection between the' supporting member and the platform, said platform" having a threaded boss thereon at the oppo- Svite face from thefsupporting member,*a

fitting having threaded engagement with I the boss, and a swivel bag-securing member n said fi ng- 5. A platform for striking bags,'an d sup porting means therefor, including a sup-' porting member ad aCent to one face of the platform, a bolt fitting the said supporting a member, an extension member having at one end threaded engagement with the bolt and at its opposite end bearing against said platform, thesaid extension member having a threaded stem "extending through the' platform, said platform having a boss at the underside, the boss being internally threaded to receive said stem and'being externally threaded, and anuton said. stem at'the underside of the boss, a fitting having threaded engagement with the, external b er within said fitting. t

In testlmony whereof I have subscribed name to this spec ficationin the of two subscriblng witnesses.
